This voice engine is available at no additional cost. In testing, the voice generally surpasses state-of-the-art voice vendors in realism, while beating them on cost and latency. ## Key Features * **Natural Prosody**: Sesame voices deliver more natural intonation, rhythm, and stress patterns in speech * **Improved Expressiveness**: Better emotional range and contextual understanding * **Enhanced Pronunciation and Spelling**: More accurate handling of complex words and phrases * **Seamless Transitions**: Smoother flow between sentences and paragraphs ## Using Sesame Voices Sesame voices can be identified by the "Sesame" tag in the voice selection interface. While there are a small number of available Sesame voices right now, **cloning Sesame voices** is straightforward, and can be done with \~8-20 seconds of audio. For tips on effectively creating new Sesame voices, see the [Voice Cloning](/platform-overview/voices/voice-cloning#sesame-voice-cloning) section. Sesame voices are still in beta, and may still have instability in inference (e.g. long pauses, or strange conversational artifacts). We regularly release updates that enhance their capabilities and performance.
